Technical Breakthrough: Shenzhen Tunsing Releases DS001TS High-Performance Copolyester Hot Melt Adhesive Film, Powering

[Shenzhen, April 30, 2026] – As global demand for eco-friendly and efficient bonding solutions continues to rise, high-performance hot melt materials are becoming essential for industrial upgrades in textiles, automotive, and electronics. Recently, Shenzhen Tunsing Plastic Products Co., Ltd., a leading provider of bonding solutions, officially released the latest technical specifications for its flagship product, the DS001TS Copolyester Hot Melt Adhesive Film.

As a mature copolyester-based bonding material, the DS001TS has once again garnered significant industry attention due to its excellent physical and chemical stability and versatile application scenarios.

The DS001TS is a thermoplastic film-like hot melt adhesive supported by a release paper backing. It is specifically designed for complex processes that require repeated heating and plasticization.

• Superior Bonding Compatibility: This product demonstrates excellent adhesion to textiles, PVC, and PC.

• Outstanding Durability: It meets modern lifestyle requirements for durability, withstanding washing at 40°C and exhibiting high resistance to dry cleaning.

• Precise Physical Parameters:

  • Color: Milky white, semi-transparent.

  • Melting Point Range: 80-105°C (ISO 11357).

  • Activation Temperature: 116-150°C.

  • Proportion: 1.15±0.02g/cm³.

In the newly released version V1.4 of the technical data sheet, Tunsing has disclosed detailed DSC (Differential Scanning Calorimetry) and rheological analysis data, providing engineers with precise processing references:

1. Phase Transition Characteristics: According to DSC testing, the film’s glass transition temperature (Tg) is approximately 5.8°C, with a melting peak observed at 95.1°C. This indicates that the material remains stable at room temperature and transitions rapidly to a viscous flow state near 95°C.

2. Viscoelastic Transition Point: Dynamic mechanical measurements show that the temperature at which the storage modulus and loss modulus cross—representing the transition from a viscoelastic solid to a viscoelastic fluid—is approximately 78.1°C. This data helps users accurately control the material state during the initial stages of heat pressing.

The DS001TS is utilized across a wide range of industries, from high-end manufacturing to everyday consumer goods:

• Fashion and Textiles: Clothing, embroidery, handbags, and luggage.

• Specialized Industries: Footwear, accessories, reflective materials, and handicrafts.

Recommended Bonding Conditions: To ensure optimal peel strength, the manufacturer recommends a multi-step lamination process:

• First Lamination: Suggested mold temperature is 130°C-160°C, with a pressure of 0.3-0.6 mpa for 5-15 seconds.

• Second Lamination: The temperature can be adjusted to 130°C-170°C, with a duration of 8-25 seconds to reinforce bond strength.

Shenzhen Tunsing emphasizes that the DS001TS specifications have been refined through rigorous technical testing. While laboratory data provides a scientific basis for industry use, users are advised to conduct detailed verification based on their specific materials and equipment before mass production.
